Changing the way Connecticut uses data.

The Connecticut Data Collaborative is a public-private partnership that advocates for the public availability of open and accessible data to drive planning, policy, budgeting and decision making in Connecticut at the state, regional and local levels. We are a user-driven organization, serving nonprofits, advocates, policymakers, community groups, and funders in using data to drive policy and improve programs and services.

In addition to providing open access to structured and processed data, we can also work with you on to solve your custom data needs. Contact us for more information.



Our data portal contains over 135 datasets that we have curated and processed into a machine-readable structure. Use our custom data-exploration tools to narrow your selection, or download raw data in bulk and explore data on your own. You can browse by topic, search by organization, or search by dataset.
